Hi all
Just signed up to the forum after reading loads of your helpful msgs about plastering woes! :) What an awesome place for help and knowledge.
I have found a number of similar threads on this subject but just wanted to get some direct advice is possible pls?
Just bought a new place (our own home, not a flipper) and started on the re-decoration process. It's an early 60s bungalow. The lounge was covered in a number of layers of old wallpaper which I stripped off (had to use a steamer...). Had a plasterer in to skim the walls as they were pretty cracked and tired. Also the plaster on chimney breast was falling off down to the bricks.
After much reading about re-decorating fresh plaster I went off and bought a big tub of contract matt, thinned it down according to the instructions (Amstead brand from dulux store). 5;1 mix. Started applying, and on one wall the skimmed plaster blistered, cracked and fell off. Tapping the wall with fingernail indicates there are other areas that are hollow sounding and clearly not secure. The plaster was definitely dry before I started applying paint, skim was done 3 weeks ago. Pics attached here to show the damage.
Bit worried about the white coat under the area that is affected. It has a white dusty finish, shown below in picture of my hand after rubbing it. Been reading about distemper. What the heck :) I thought that was something dogs caught...
Anyway, pls, pls can someone advise on best way to proceed that will be least time/most effective. I am now up against it with pending delivery/fitment of new fireplace and carpets. Oh joy....
Thanks in advance,
Mark
PS I am in Malvern so if any plasterer members want to take a look and quote to help me out, pls msg me. I need an expert :)

You definitely need to get in touch with the plasterer you used. It does look like distemper, if so it needed different prep to just going over nice stable emulsion.
 
Hey all, thanks for the replies. Have already had the guy back; twice! First couple times in an attempt to get a better finish. The first pass looked like a lunar landscape. Second attempt wasn’t much better. I then spent best part of a week making good with filler and sanding. I have just given up on him.
So I am calling in another guy I found who came highly recommended to take a look and quote. Wanted to get views from here so I can be better prepared when he comes. As I mentioned in original post. If anyone is in the Malvern (Worcestershire) area and would like to quote, pls msg me, I would def be interested.

@essexandy said he thought it could be distemper. What will need to be done to prep if it is? Want to make sure the new guy does the right thing…
Thanks for all the help
Mark

It’s got to come off unfortunately, but as others have said, you need to contact the plasterer. Everyone gets caught out once in awhile, and hopefully you’ll get an amicable solution.

Had to sort out a similar problem a few weeks ago for a customer caused by another plasterer. Big patches of skim delaminated but still attached to the wall. Not distemper but complete lack of suction control as the wall just too dry.

There was also about a two foot square patch in the middle where it had probably shelled off on the 2nd coat and they’d tried to patch it in with fat :ROFLMAO:

Patched in with fat you say, this has all the hallmarks of another @JessThePlasterer bodge job?

No, most of my work was new. And too old to change working practices for a few little jobs.

Tried it on a couple of jobs, nothing remarkable, just because I could really. No PVA. bareback. Total fail flash c**t both times ! May have been ok used as standard but that was the USP so gave up. Seemed a bit s**t to feel tbh so just a big load of pish is my evaluation on that one mate. You know when your mixing it , I think anyway (y)

Saw that clip a while back - pretty sure


That was decorators - steamed the room of paper

Next day went to prep and paint and blamed the plasterer/plastering from ages before and saying it wasn't pva'd

Yeah made that cock-up with a steamer on my own place years ago when in London.
